This is how car thieves can steal keyless entry-equipped cars

Car keys are increasingly getting high-tech. From conventional mechanical keys to remote keys and finally to keyless entry that obviate the need to fish out the key from owner's pocket to unlock and lock the car. This obviously offer nice convenience factor to car owners...and even to car thieves. Yep, car thieves can still drive keyless entry-equipped car away which is not only easy to pull off, but dead cheap as well. Wired Magazine reported that Qihoo 360, a Beijing-based security firm, had proven the possibility through a relay hack.

How does the relay hack work? 

For keyless entry to work, car owners need to be standing within close proximity, roughly 5 feet away from the car, to pick up the signal from the key fob. What the relay hack does is it enables would-be car thieves to extend the signal from the owner's key fob to a radio signal device that tricks the car into thinking the key fob is within close proximity. The short video above by Jun Li, a researcher from Qihoo, demonstrates how the hack is executed.

For this hack to work, it will require 2 people and 2 radio signal devices. One thief tails the owner with the device in hand. The device will then copy and transmit the signal from the owner's key fob to a separate device held by the thief's accomplice who is within close proximity with the car. The car receives the signal from the device and tricked into thinking it is receiving signal from the owner's key fob, the car door is automatically unlocked. 

Simple indeed. As well put by Jun Li, "You're working in your office or shopping in the supermarket, and your car is parked outside. Someone slips near you and then someone else can open up and drive your car. It's simple." 

The price?

How much it costed Qihoo to put together the radio hacking device? Well, get this: $22 (RM 95)! Dead cheap indeed. Also, according to carmudi, the hacking system's range is increasing, enabling car thieves to unlock the car even if the owner's key fob is more than a thousand feet away. Is this the end of the world?  

How to prevent the hack from occurring?

Thankfully there is a way. As suggested by Qihoo's researchers, automakers and component companies can prevent the relay hack by tightening the timing constraints in the call-and-response communications between the key and car. In other words, if the signal is copied and transmitted too far away, the fraudulent transmission can be rejected altogether. 

Owners can also do their part by keeping the key inside a Faraday bag that blocks radio signal or inside a metal box such as a refrigerator.   

Let's hope the auto industry can get their act together to forestall future attacks before it becomes too easy for car thieves. 

   

BMW E30 M3 a racing legend

Sport Evolution (aka Evo III) model

Year 1986 has to be the sacrosanct year for the BMW aficionados as it marked the beginning of a legend that stood the test of time until the present day. The M3 badge makes its presence felt all thanks to Munich's racing aspiration. The venerable badge gestation was instigated by the E30 generation as a homologation special for entry to Touring Car racing, where it would lock horns with the likes of the W201 Mercedes-Benz 190E 2.3/16V in the DTM series.

Available either in 2-door coupe or convertible form, the E30 M3 was a star machinery, with notable accolades including winning the 1987 World Touring Car Championship drivers title, Top Sports Cars of the 1980s awarded by Sports Car International in 2004 and the "5 greatest drivers cars of all time" under Automobile Magazine 25 Greatest Cars of All Time. 

To keep the car competitive in racing and adapt to homologation rule changes, special editions model were produced. Due to the homologation rules roughly stating that the race version must reflect the road-going version, special editions model were rolled off the assembly line where the differences between standard M3 and special editions model include more power out of the stonking S14 engine, improved aerodynamics, lighter weight and bigger wheels. The special editions model were christened Evo II and Evo III (Sport Evolution).

 

It all started with the Evo II available in 1988. The latter retained the 2.3 litre S14 naturally aspirated 4 pot from the standard M3, albeit with a bump in power from 197 hp to 217 hp thanks to higher compression ratio, revised intake camshaft profile and improved exhaust camshaft timing. The wheels had also grown in size (16 x 7.5 inches), weight had been shed off thanks to lighter bootlid, and front splitter and rear spoiler took care of the aero department. Only 500 Evo II models were available.

In 1990, the more potent Evo III, or Sport Evolution, hit the scene with a larger 2.5 litre S14 4 pot which boosted output from 217 hp to 235 hp with higher lift intake and exhaust camshaft fitted.

Adjustable front splitter and rear wing were fitted and the front foglights had been replaced by brake ducts. Only 600 examples were made.

Thanks to the special editions model, the E30 M3 gained entry to the Touring Car racing and performed impeccably. The car had to its name 2 European Touring Car Championship titles, 2 British Touring Car Championship titles, 4 Italia Superturismo Championship titles and 2 DTM titles.

Apart from Touring Car racing, the E30 M3 also partook in rally racing, clinching victory in the 1987 Tour de Corse driven by Bernard Beguin and the 1990 Irish Tarmac Rally Championship driven by Bertie Fisher.

Given the number of accolades in the bag, the E30 M3 has to be among the most competitive racing machine to have ever graced a race track.
